SSB and CW Exciter
My SSB and CW exciter design from 2007 directly generates RF at the
output frequency using a DAC and an FPGA. It is controlled by
Ethernet. All the design files are located in exciter.zip. When you
un-zip this file be sure to preserve the directory (folder)
names. You will also need the QUISK
software for the PC.
An article describing my exciter appeared in the May/June 2008 issue of
QEX magazine. The article
is available here.
The software is in the following directories:
The FPGA program for SSB is in Altera/duc1.
The FPGA program for CW is in Altera/duc1cw.
The FPGA program for a two-tone test is in
The FPGA libraries are in Altera/LocalLib.
The AVR microcontroller software is in AVR/Duc1.
The PC board files for Eagle are in Eagle/DUC2.
